CAR-COUPLING.

SPECIFICATION forming' part 0f Letters Patent NO. 787,954, dated April 25, 1905.

Application filed June ll, 1904. Serial No. 212.098.

To rl// 107mm, it nl/ty concern:

Be it known that I, Josevi-1 SNYDER, a citi-` zen of the United States, residing at Harrisburg, in the county of Dauphin and State of Pennsylvania, have invented certain new and useful Improvements in Car-Couplers; and 1 do declare the following to bea full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

'lhis inventton relates to automatic carcouplers of the Janney type; and it has for its object to provide a durable and inexpensive locking device of few parts and easy operation; and it consists in the parts and combinations of parts hereinafter described and claimed.

VIn the accompanying drawings, forming a part of this specification, Figure 1 isa plan view of my improved coupler; Fig. 2, a longitudinal vertical section on the line 2 Q, Fig. l, showning the locking-pin in its locked position; Fig. 3, a longitudinal horizontal section on the line 3 3, Fig. 2; Fig. 4, a vertical section similar to Fig. Q, showing the lockingpin raised andsupported in its unlocked position; Fig. 5, a longitudinal horizontal section similar to Fig. 3, showing the knuckle in the act of closing; and Fig. 6, a detail perspective view of the locking-pin.

Similar letters refer to similar parts through out all the views.

Referring to the drawings, A represents the draw-head, and B the knuckle, of an automatic car-coupler of the J anney type, which may be of the usual or any preferred construction, although l prefer to have the knuckletailpiece u, to extend through an opening formed therefor in the side wall of the drawhead when the knuckle is in its coupled or closed position, as shown in Fig. 3, in order to gain the additional safety afforded thereby in the event of the hinge-pin of the knuckle breaking when in use, in which event the tailpiece through its engagement with the walls of the opening will prevent the cars pulling apart and the knuckle dropping to the track.

The opening for the locking-pin D is formed vertically through the draw-head, as is usual; but the portion thereof, C, which extends through the upper half or wall of the drawhead is square, approximately, and has formed in its `front wall a shoulder E in order to provide a support for the locking-pin when it is lifted or raised to release the knuckle. The opening (l receives the body or heavier portion of the locking-pin, while its lower end is reduced and of triangular shape, as best shown in Figs. 5 and V6, and extends through a triangular-shaped opening' F in the lower wall of the draw-head.

The locking-pin D is Yformed in two parts or sections c and d, the part or section c having the usual horizontal flange e to rest on the edge of the opening C and being' hinged to the lower part or section (l. At the rear side part or section c is cut away on a somewhat curved line, as at f, in order to provide space `for a pin 1I, which is inserted through the side of the draw-head and extends transversely across the opening C. The lower part or section (Z of the pin D is reduced to forma shoulder 1 at the rear of the pin, which is adapted to engage the pin H when the locking-pin is raised or lifted to uncouple the cars. On the front face of the lower part or section l of the locking-pin is formed a groove J, which is adapted to engage the shoulder E when the lower part or section of said locking-pin is tilted forward by the pin Hand to thus support said pin in its raised position until the knuckle is swung out and its tailpiece strikes a sliding blow against the lower end l( of the lockingpin and pushes it back, as shown in Fig. 5, and thus disengages the groove from the shoulder and permits the pin to drop down and rest upon the tailpiece of the knuckle.

The swinging in of the knuckle-tailpiece in the act of coupling permits the locking-pin to drop down in front thereof, and thus lock the knuckle in position to complete the coupling.

The triangular end piece K of the lockingpin is formed with a slight bulge or is thickened, as at L, so as to insure contact with the tailpiece of the knuckle, and the opening F is of a size to provide space for themovenient of the pin.

By reason of .forming the locking-pin in two parts or sections and hinging them together l am enabled to readily tilt the lower IOO part or section thereof forward to engage the shoulder E, and where, as is often the case, the coupler is driven back under the car or the bumper from one to three inches by impact in coupling lthe cars may be coupled or uncoupled easily, because the upper part of my pin leans forward and provides space for its movement.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A car-coupler comprising a knuckle, a-

to engage the shoulder formed in the lockingpin opening.

2. A car-coupler comprising a knuckle, a draw-head having a vertical opening for the locking-pin, the upper section of said opening being square and the lower section triangular in cross-section, a shoulder formed in the upper section of said opening, a lockingpin formed of two sections hinged together, the lower of said sections having a groove adapted to engage the shoulder in the opening to support the pin in its unlocking position, and lower end of said lower section being triangular in' cross-section, a shoulder formed on the rear side of the lower section of said locking-pin, and a transverse pin for engaging said last-named shoulder.

In testimony whereof I aix my signature in presence of two witnesses.
